Disclosed herein is a perpendicular magnetic film comprising a spinel thin film which is formed on a substrate, which contains Fe as the main ingredient and further contains Co and Ni, and which has a coercive force of less than 3000 Oe, the plane (400) thereof being predominantly oriented in parallel with said substrate, the spacing of the plane (400) being not more than 2.082 Å, the molar ratio of Co to Fe being 0.005 to 0.32 and the molar ratio of Ni to Co being at least 0.6. |
